Abstract

Real-world studies on-board newbuild vessels powered by modern LNG engines were conducted at several load conditions at-sea and in harbor. Compared to earlier on-board studies, the methane slip variation was suppressed, and lower methane levels could be achieved at lower engine loads as well. Further reduction in methane slip could be achieved with engine piloting a new combustion concept. Measured results could be reproduced with the STEAM Ship Traffic Emission Assessment Model utilizing new parametrization for methane. Studying the normal operation of two LNG vessels (Ro-Pax ferry and a cruise ship) exhibits different engine use profiles of the vessels and may help to identify opportunities to further reduce methane slip by operational choices of the vessels.
